Be it known that I, AUGUST BASSE, of Quincy, Adams county, State of Illinois, have invented certain new and'uscful Improvements in Machines for Carving'Wood,-Bone, Ivory, and other materials; and I do hereby declare -the following description and accompanying drawings are sufficient to enable any person skilled in lthe art or science to which it most nearly appertuins toma'ke and use my'said invention or improvements without further invention or eperiment.

The-nature of'my invention consists in conveying the motionrfrom the tracer `to the cutter by means of slotted levers connected by a link, which' may be adjusted to cut the figure carved either the same height .or

4 higher or lower than the pattern; an'din constructing the coupling, which connects the cutter-shaft to the traverserod that works it, with a spring to press the coutter'lshaft against the traverse-rod, and .prevent the cutter from chattering; and in construct-ing the couplings which 'eonnectgthe levers (which -convey the motion from the tracer tothe cutter) to the traverse-rods with clamping-nuts, sothat when the tracer and cutter are adjusted, thenuts may be clamped on the screws to prevent them from turning. .In the accompanying drawings- Figure 1 is a front elevation of a carving-machine with my improvements. Figure 2 is a plan or top view. i i

Figure 3 is an elevation of the right-hand end.v In these drawings, A is a rectangular frame, supported byV four legs. Al is alhorizontal shaft, mounted on proper journal-boxes, fastened to the frame A, and provided with a pulley, A2, for a belt from somo moving power to drive the machine. A3 is a cone, fastened to the shaftl A1, and carrying the belt B and conc Bl and shaft B2. The gear B3 is fastened to the shaft B2 tovdrive the gear C, and carry the shaft Cl with the screwC2,

"and turn a'gear directly behind the gear C3, and fastened to the screw C4 t9 turn it, which screw, C, turns in a journal-bok fastenedlto the frame A, and traverses the carriage D on'ways D1, on the front bar of the frame A. The' rotating chuck D2 is provided with a shaft turning in boxes in the carriage D. This chuck carries the block D3, which is clamped to it by the clanrps D2, upon which block the figure to be carved is cut. To turn the chuck D2, I fasten the pulley E to the shaft B2, which pulley carries the bandvE, and drivesthe pulley E2 and the shaft-E2and gear F, which turns the gear Ifl and shaft F2. Both the last-namcd shafts are mounted in journal-boxeson the frame A. The gear F1 is not fastened directly to the `shaft`l5`2, but to a tube, F3, which extends through the journal-box, and has 4the gearG'fastened to its inner end, (shown bydotted lines in g. 2,)

'which gear, G, turns the gear G1 o n a stud in the f1-ame, and carries the gear G2, whichtu'rns loose o'n the shaft F2. Between the gears Grl and G2 there is a clutch-box, arranged to traverse .on the shaft, and worked by the lever G2, soas to lock either of thegears G or G2 tothe shaft F2, to turn it in either direction, as' desired. The shaft F2has a groove cut in it lengthwise for the feather of the screw H, which is fitted to theshaft, and traverses on it`. The screw H turns in a. journal-boxH, fastened `to the carriage D, which screw, H, is shown in dotted lines in iig. 1, and turns the chuck D2, by working in agear fastened to the shaft H2 of the chuck.'

It will beperceived that by this arrangement of the gears and screw H, the chuck is turnedinleither direction without regard to 4the traversing of the carriage. On-the' opposite end o f the ways D there is a carriage,

I, similar to the carriage D, with a rotating chuck, Il, and clamps, I2, to hold and carry the pattern I2 of the ligure to be carved. The carriage I is traversed by the screw K, turned by thegear Kl, which isturned by the' geen C2, lbefore described. The shaft E3 extends across thel carriage D, on to the carriage I, and ha's a v groove in it for a feather in the'screw J", which turns in the journal-box J1, and turns the gear J2 onthe shaft J2 of the chuck Il, to. turn it independently o f the traversing of the carriage I. The gear C, before described as turning the shaft C, is fastened to a tube that turns loose on the shaft and extends lthrough the journal-box,

'and has. the geur a fastened to it, which-turns the gear al and drives the gear a2 in the opposite direction from the'geur a, which gear, a2, also turns loose ou the shaft C1. A clutch-box is arrangcd on the shuftvCl, between the gears 'a und a2, and is worked by the lever K2, so as te lock either gear to the shaft and turn it in either dircetion,'as required, and move the carriages D and I to the'right or left, as may be desired. I make two stands, L and L1, and fasten them to the frame A, one at each end of the ways DI, and connect'their upper ends to the top bar L2. The stahdL is fastened to the stand L by the screw L,-so that it may be adjusted higher.

or lower at pleasure. Y The stand L3 has two journal-boxes for the tube M to turn in, which is provided with a pulley, M1, carried by the band M2 from the pulley M3 on the shaft M2, which turns in stands fastened to the frameA, and is carried' by the band N from the pulley Nien the shaft A1, to the pulley N2 on the shaft M.

The pulley Ml has `a groove for the band M2, whichfpasses entirely around it, and th'en passes around the studpulley Ns'before it returns to the driving-pulley M2. AThe stud cf the pulley N is fastened in a slide, arranged to be adjusted on the arm N4, fastened to the stand La, so as to -tighten the band M2 as required.

.- The tube M hasa feather iu it, working in a groove in the cutter-shaft P, to turn it and the cutter I,

which is fitted to a socket in the shaft, and secured by. a set-screw. 'The cutter-shaft P extends up through .the

lin the opposite direction from which they moved before, so-that the tracerv tube Minto the coupling-link?, which connects it to the traverse-rod P3, which works through an arm, PL, from the stand L3. The rod P3 has a groove in it, traversing on the pin in the stand P4. The spiral spring b2 around the shaft P acts against a nut on said shaft to keep it constantly pressed against the point of the rod P3, and counteract the effect of any wear ofthe parts, and prevent the cutter from chattering.

The rod P3 is connected bya joint,-Q, and 'swivel-link, Q1, which turnson the screw Q2, fastened to the lever Q3, which traverses the cutting-tool up and down to form the gure on the block D3. The upper part ofk the link Q1 is an opennut with a tightening-screw, so that by turning the link the cutter may be adjusted vto the proper height, and then secured by the tightening-screw in the open nut. The lever Q3 vibrates on the pivot Q* in the bar L2, and has a slot in it for the pivot of the-link R, which connects it with the lever R, which vibrates on the pivot R2 in the stand L. This lever, Rl, is vibrated by the traverse-rod R3, which holds the tracer R4 acted upon by` the pattern I3.

The traverse-rod R3 is connected to the lever B.l by the screw S, swivel-link S1, and joint S2, by which the tracermay be adjusted to the pattern, in the same manner as the cutter to the block. AThe'stand S3 is fastened to the stand Ll bythe screw S, and it maybe adjusted higher or lower, as desired. The stand S3 has.

two horizontal rings, T T, which surround the traverse-rod R3, which is three-sided; and there are threestands, Tl, rovded with rollers, fastened to each of the rinfvs T T to hold and uide the traverseerod as it moves u P o 2 g P and down with very little friction. Ono of the stands, T1, in each of the rings may be pressed forward to press the roller against the traverse-rod, and the rod against the other rollers by the screws T?. =The arm T3 extends up from the stand S3 to form. a fulcrum for the lever T4, which extends through the traverse-bar R3, and has the adjustable weight T5 to press the `tracer against thev pattern. The screw V turns in the lever T4, and should be set so that its point will rest on the ring T, and prevent the tracer from being depressed by the Weight below the plane of the pattern. The lever Vlis hinged to the "lever T4, to lift it with the traverse-rod and tr'ace'r and cutter, when required. The bar V2 is fastened to the carriage D, and has twostops on it, one of which is seen at V3, which stops arev adjusted by the screws` V* and V5 to act on the bell-crank W, which is connected by the bar d to the lever K2, and is so arranged as to throw the clutch-box from the gears a and a2, and stop the traverse motion of the carriages when the tracer comes to the edge ofthe pattern or at the proper point. To make the carriages traverse slower and the chucks turn slower also, as the tracer andcutter work from the centre towards the circumference, I fasten the plate WJ, which carries the rack W2, to the carriage D, so that it moves with theccarriage and turns a pinion on the under side and fastened to the gear W3, which gear turns on a stud fastened to the frame A, and carries the rack W4, which moves the belt-shipper W5, and moves the beltB from right toleft on the cones, diminishing'the speed of shaft B2, and the traversemotion of the carriages and the rotationsof the chucks. 'The rack W1l has slotsv in it, fitted to guides on which it traverses, the guides being fastened to the frame v i To operate this machine and carve a figure, the pattern of theiigure to be carved is clamped on the chuck Il, and the block upon which the figure is to be eut is clamped to, the chuck D, and if the figure is to be c ut the same height of the pattern, the link R must be set'in the middle between Q2 and S; but if theligure isA to be cut higher than the pattern, the link must be moved to the left towards Q2, and if lower than the pattern, to the right towards 12,1. The tracer, R4, isadjusted tothe centrepof the pattern, and the cutter, P, to the centre of the block D3; and the belt B, at the large end of the cone A3,'and the other parts being all adjusted, the machine is set in motion. *The pattern moves the tracer up 'and letsit down, which tracer-moves the cutter with a corresponding motion, while it is turned rapidlyto cut away that part of the block with which it comes in Contact, and form the figure of the 'pattern on the block D3, the chuck being turned and the carriages traversed in unison. When the carriages have moved so far as to bring the tracer the desired distance beyond the edge of the pattern, one of the stops on the bar V2 moves the bell-crank W, and movesthe clutch from the gear,`and the vcarriages stop. I now turn the link Q1, and move the cutter down a proper distance for a new cut, and move thelever K2 to throw the clutch-box into the opposite gear, and traverse the carriages and turn the chucks and cutter will move from the circumference into the centre and complete the {igureon the block D?. To carve `a figure the 'saine size of the pattern, the gears C3 and K1 must be of the same sire.4 To Amake a ligure larger than -the pattern, diminish'the gear C3 and increase the gear K1; and to carve the 'gure smaller than the pattern, increase the size of()3 and diminish the size of Kl. To make the ligure carved the same as the pattern, the clutch at the end of the lever must be moved 'to lock the .gear and make the chuck D2 turn in the same direction with the pattern. To make the iig-ure the reverse of the pattern, the clutch must be moved to'make the chuck D2 turn in a direction opposite to thatof the pattern.

I contemplate that with a single lever, having its fulcrum between Q2 and S, a concave gure may be carved Having described my improvements* I claim conveying the motion from the tracer to the cutter by means oi" the slotted levers Q3 and R', and link R, which may be adjusted to cut the figure carved the same height ofthe pattern, or either higher or lower than the pattern.

I also claim constructing the couplingPz, with a spring to press the cutter-shaft against the traverse-rod,

froma convex pattern', or a convex gure from a--eoncave pattern.

substantially as described for the purposes set forth.

I claim constructing the couplings QVand S2, with clamping-nuts, as described, so that when the tracer and cutter are set or adjusted, the nuts may be'clamped upon the screws to prevent them from turning.
